NASA's James Webb Space Telescope (JWST) has taken a superb new high-resolution image of stellar gymnastics in the rare Cartwheel Galaxy on Tuesday, August 2, 2022.

Cartwheel Galaxy was formed by a chaotic cosmic collision.  James Webb travels back in time, captures a black hole and new stars in the strange Cartwheel Galaxy.

JWST has observed the Cartwheel Galaxy's chaos and reveal new details on star formation and the galaxy's central black hole. It is a rare sight.

This image depicts offers a new perspective on the change of the Cartwheel Galaxy over billions of years. This image depicts how the Cartwheel Galaxy has changed over billions of years.

The Cartwheel Galaxy, located in the Sculptor constellation, is about 500 million light years away and measures about 150,000 light years across.  It is a rare "Ring Galaxy".

Its appearance is similar to a wagon wheel, which is the result of a high-speed collision between a large spiral galaxy and a smaller galaxy.

Scientists believe that it was probably a spiral galaxy similar to the Milky Way, and the collision had the greatest impact on the galaxy's shape and structure.

There are two rings in Cartwheel Galaxy:  a "Bright Inner Ring" and a surrounding "Colourful Outer Ring".

In the spokes connecting the two rings, there are also areas of intense star formation, which appear to be remains of the galaxy's spiral arms.

Both rings expand outwards from the collision's centre like waves in a pond after a stone is thrown into it.

Inner Ring - The inner ring that surrounds the relatively old stars in the galaxy's centre is mostly made of hot, bright dust, along with some massive clusters of young stars.

Outer Ring - For about 440 million years, the outer ring has been expanding from the collision's centre.  When it expands and collides with the surrounding gas, stars form and illuminate the surrounding dust.

Karl Gordon at the Space Telescope Science Institute says, "This dust is telling us there’s lots of star formation going on, maybe even more than we thought."

This image also revealed a region of star formation, much brighter than expected, at the bottom right of the galaxy.

They will learn more about how the Cartwheel galaxy is evolving and what it might look like in the future, as they continue to analyse the image.
